5-6 and 226 lbs. Size 42 waist, 30 inch inseam. My KHS mtb bike is a size 17, and it is extremely comfortable. I had a size 14 MTB, and I grew to loathe it due to it being too short from the seat to the handle bars. The seat would dig into my back while the stem would scrub my belly. Good fit was important to me in buying the new bike. I really don't know what size my Bianchi Campione is, but it fits just right. When I ride it, I don't get all I want of it, but I certainly get all that I can stand before I stop. I mean to measure it sometime and see what size it is. I just need to figure out how to take an accurate measurement. - Ted
